Rosemary - What to do if infested with mildew?
Mildew is one of the most common fungal diseases in plants. They recognize an attack on the thin, white layer, which makes the leaves look dusted with flour.
Real and wrong mildew
There are two different types of mildew. The powdery mildew occurs in warm and dry temperatures, which is why it is often referred to as "fine mildew". Here, the fungus settles mainly on the stems and on the leaf surface. Mildew, especially in damp weather, has ideal conditions and causes very stubborn, white deposits.
Combat mildew naturally
Affected leaves must be removed immediately and either incinerated or disposed of with the trash - under no circumstances may they be left on the compost. Otherwise, the infested plant is sprayed with a milk-water mixture (100 milliliters of whole milk per 900 milliliters of water) or a garlic infusion (two to three crushed garlic cloves with boiling water for at least an hour and then allowed to cool) sprayed. The treatment should be done several times.
Tips & Tricks
Chemical pesticides, the so-called fungicides, should not be used on herbs intended for consumption, such as rosemary.
